well, it is same security chip, which was introduced back in ST-V, and was widely used in NAOMI games, pretty well researched by now, we got all the decryption keys and everything ~2 years ago (heh, I think it was me who brute forced most of keys for STV/M2/M3 games )

so, having all this knowledge and modern emulation/debugging tools is pretty easy and straightforward to make any kind of hacks...
